Got this on a whim to see if it would work for measuring .357 Magnum reload velocity. Didn't know how useful it would be, so I didn't want to spend three times as much on a "name brand" version.Turns out it works just fine. I started with nerf darts, then bb's, then took it to the range, and it worked like a champ. I had it mounted on a cheap plastic camera tripod that worked just fine. I thought I might have to build a sunshade for it, but it worked fine in bright sunlight and under the shade roof at the range.It didn't miss a single round out of 60 fired, except a few that were due to operator error, where I forgot to reset it after reading the measurements (by default it displays the reading for a few seconds, and then displays "--" waiting for the next shot. Then you can use the arrow buttons to scroll through the readings.) Batteries lasted through a 2-hour session at the range.I had it about 3 feet from the muzzle. When I was firing the magnum rounds, I noticed the unit swaying a bit from the shock wave. I think when I start using it with high-power hunting rifles, I will keep it about 6 feet from the muzzle to avoid damaging it.Mine also came with a spare support rod and "detection bar", so if I do accidentally hit or damage it I might be able to repair it. This was not mentioned in the listing, so I added a star!Only thing I didn't like is that it defaults to meters per sec, when I wanted feet per second. So every time I turned it off/on (frequently, to extend battery life) I had to make sure to change it to FPS. It would be nice if there was a permanent way to change the default.Not sure about the accuracy, and I haven't investigated a way to cross check it yet. The internal calculations involved are pretty simple, so I'm hoping it is ok. The measurements I got seemed in the ballpark for the reload data I have.

I got this chronograph a few days ago, but today was the first chance I had to test it out. When I opened that package, I saw that it needs four AA batteries, so I knew I had to get some on the way home from running some errands. By the time I got home, I only had a few minutes till the sun would go down. I managed to put the chronograph together quickly; it's super simple; and I love the fact that it came with an extra light bar, an extra rod, and a couple of extra screws. I ran in the house and grabbed couple of air rifles, one of a known velocity, the other was one I wanted to test. By the time I got to shoot, the sun had already dropped below the treetops, but the chronograph still gave me good consistent readings. (Note: my old chronograph would NEVER have given me any readings with that low level of light!) The low-power target rifles I was testing gave me the results I expected. The .177-caliber one is a known 4.4 fpe rifle; and the .22-caliber version was giving me readings of 125 mps (410 fps); with my 13.43-grain pellets, that's 5 fpe, slightly more power than the .177 rifle, which is what I had expected, since they are identical (Haenel mode 1 rifles from the 30s) except for caliber. So far, especially for the price, I am impressed with this chronograph! Thank you.

I've had this since May 2024. It seemed a little flimsy so I've left it set up on a tripod and just move it all together outside. No big deal for my situation though but I don't think disassemble and reassemble would be such a good idea for long.I've probably shot around a 1000 pellets from .177 to .25 caliber and 22 LR through it. No problems and minimal errors show up. I use it in a shaded spot. I just use it for velocity (after you hit the FPS button each on/off cycle) and out of routine calculate the ftlb of the energy myself. I feel confident in the accuracy, I mainly am looking for ballpark increase/decrease. I have compared it to documented velocities and get (+-3%), so that's good by me. I didn't want to tie up a lot of $ for what I'm doing. I'm happy with it. Honestly I didn't think it would last this long! If I need to replace it at some point, I'll get another just like it.

If you looking to guage a ping pong ball indoors. Sure. Useless for anything else. Looks like I received a refab. There is a trail of something across the top casing and lead inside the top of the case at the first sensor, at unboxing. Threw a pen through the uprights. Pretty much 1 (plus or minus) meter per second. Tested on everything from an airsoft to a .357 mag. Nada. Hey, xuhal... this is why there are new and used options. Don't re-pakage a turd and sell it as an egg.

Works very well for our use. Just as accurate as some of the expensive models. Very easy to set up and disassemble.

This chrono seemed to work well, what i did not really like about it was the area for measuring the speed of an object is too small, Resulting in some real bad damage, MY FAULT but just something to consider if you were shooting through this.

No complaints. It does what it's supposed to do.
